Former Spice Girl Geri Horner Tweeted the happy news after she gave birth to a baby boy Saturday morning

Former Spice Girl Geri Horner, who was known as Ginger Spice in the girl band, took to Twitter almost straight away to share the happy news after giving birth to her son, named Montague, on Saturday morning.

She posted: “Christian and I are delighted to announce our baby boy was born this morning weighing 7lbs 8oz.”

The news comes less than a day after Geri posted a picture of herself and her baby bump on Instagram, with the simple message “Hello.”

While it is Geri’s second child, following the birth of her daughter Bluebell Madonna in 2006, it is her first with husband Christian Horner, who she married in 2015.

And Geri’s new member of her family also shares his birthday with Geri’s former bandmate Emma Bunton.

Hours earlier, Geri posted a picture of the pair in their Spice Girl days in a special happy birthday tribute.

And she got this Tweet from Emma in return:
